Heating the food
Not the best capture but I wanted to show my solution. In the past 4 days, we've had a low of -10, second coldest day in Oregon history (my area of Oregon). Even with the heat lamp, ice crystals are still forming on the top of the solution at 9 degrees F. I was amazed to find them at the feeder the morning of -10, that they had survived the night.
They feed from the warm side until it gets around 20 degrees. Once I see them on the other side of the feeder, I unplug the lamp.
